Question 1

Formulate the null and alternative hypotheses for a hypothesis test.

The owner of a football team claims that the mean attendance at games is greater than 75,100.
◦ H0: μ < 75,100
Ha: μ = 75,100
◦ H0: μ = 75,100
Ha: μ < 75,100
◦ H0: μ = 75,100
Ha: μ > 75,100
◦ H0: μ > 75,100
Ha: μ = 75,100

Question 2

Formulate the null and alternative hypotheses for a hypothesis test.

In 1990, the average duration of long-distance telephone calls originating in one town was 8.5 minutes. A long-distance telephone company wants to perform a hypothesis test to determine whether the average duration of

phone calls has changed from the 1990 mean of 8.5 minutes.
◦ H0: μ = 8.5 minutes
Ha: μ < 8.5 minutes
◦ H0: μ = 8.5 minutes
Ha: μ > 8.5 minutes
◦ H0: μ ≠ 8.5 minutes
Ha: μ = 8.5 minutes
◦ H0: μ = 8.5 minutes
Ha: μ ≠ 8.5 minutes
